Abstract
Antenna elements include a metallic square ring patch and a metallic square ring slot to transmit or receive radio frequency (RF) signals. The antenna elements use several dielectric layers that are separated by a low-dielectric foam layer upon which the square ring patch is positioned. The disclosed antenna elements may be arranged together in an antenna array that is tunable to collectively generate or receive RF signals. In particular, the antenna array functions as a 256-element transmit/receive half-duplex antenna, operating in transmit or receive mode for half the time. The antenna array includes a radiator block, a transmit/receiver (T/R) amplifier block, a beamformer block, and a distribution network block.
